RFC: Delete protection from within Myth

I find that I am accumulating more and more music specials in my
"Watch Recording" screen. I want to keep these recordings handy and
have thought about how best to do it.

Enhancement: Delete protection from within Myth
=============================
- Add a field to the database (recordedprogram table I think) called
"nodelete", this would be a bool to indicate that the recorded program
is not to be deleted (strangely enough). If this field is missing or
false then deleting is allowed.

- In watch recording screen, when displaying the
PlaybackBox::showActionPopup, grey out (make unavailable) the "Delete"
option if the nodelete bool is true, or provide feedback to user
another way.

- Also grey out the delete options on the popup in the delete recordings screen.

- Add menu items to the "Storage Options" to toggle the nodelete flag
for a recording.

- Update mythweb to honour the nodelete flag.

Any thoughts if this is the "right way" to implement delete protection
and whether it could make it into trunk.

Cheers,

Roo

Another option:

Get a really big stick, hammer nails through it. The next time someone
deletes one of your recordings.. well, I'm sure you get the gist of the
idea ;-)

Sounds like an excellent idea. I, for one, am tired of people deleting my
recordings.

Sounds like somebody needs to pickup last years SoC project
to make mythtv multi user aware.

And, I think that would apply as, perhaps, a better approach for Roo,
too. With the multi-user approach, rather than "can't delete" flag that
anyone can change, files could be protected according to MythTV user
permissions (thereby allowing a "root" or "admin" user to have final say
over the matter), some users could be restricted from deleting anything,
others could be allowed to delete from their own personal view of the
available recordings, but without affecting other users... It leaves a
lot of possibilities (which were discussed on the list during the SoC
project).

I have thought about that as well as there are a couple of reasons I
proposed what I did.

- I have deleted recordings _I_ wanted to keep before, it is usually a
case of "muscle memory"; exit recording and by habit delete it.

- I didn't intend for the "Delete protect" to stop any one deleting it
if they really wanted to, just shift that operation out of the
"normal" dialogs (when lprotected) and requiring an "unprotect".

- I thought this might tie in well with the "recording groups" /
"storage groups".
I change the "storage group" of the shows I want to save (probably by
changing the recording group or maybe some other way) and they can get
moved to the "storage group" location, possibly a raid array, then set
the delete protect flag.
<I need to look into this>

- And most importantly, it is something I think I can code up. (I
think the multiuser SOC is beyond my skills at the moment)

if I found myself deleting recordings I didn't want to delete I would
transcode them to .avi and move them from recordings to Videos next
time... I think even you wouldn't happen to delete them there ;-)
